Let us not grow tired of doing good, for in due time we shall reap our harvest, if we do not give up. Galatians 6:9
Adelphia Classical Christian Academy was founded in 2014 as a K-12 Private School Satellite Program (PSP) in Orange County, California. Adelphia was founded by Diane Bartosch, Anastasia Tzoytzoyrakos, Christian Bettenhausen, and Tiffany Bettenhausen. Adelphia’s founders sought to form a family-oriented, classical, Christian program—Adelphia Classical Christian Academy. Adelphia was founded as a classical three-day-per-week program that intentionally sought to balance a student’s academic workload with quality family time in a Christian environment. Mary Beaver (a former Adelphia teacher) joined the Adelphia Administration team in 2020 and is the Co-Founding Developer of Adelphia’s Classical Program. She orchestrated and led the initiative of helping to refine Adelphia’s classical approach, and in reconfiguring Adelphia as a Classical Academy.
